Yes. But, again, the power to the output amps is not regulated, it is created with H801-H802 bridge with centertap from xfmr Og-Og winding and tfhen fitered to create +/-35V by C003-C004.
35V feeds other amps.

Same as I said above, if you want to find out why it is low. Start disconnecting loads. Find out which one brings it down, then investigate.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
